Chemical+Energy

= = = CHEMICAL ENERGY!!!!!!!! = ===Chemical energy is the energy inside substances we use, such as food and petrol. The energy is not released until these substances are changes into others. This happens when we eat food. Our stomachs digest the food and produce Chemical energy for our bodies. It also happens when we burn fossil fuels such as coal, oil and gas. Burning releases the Chemical energy so that we can use it. In the engine of a car, petrol is exploded within the cylinders, forcing the pistons to move up and down. Thus movement is transferred to the wheels, causing them to turn.===

= EXAMPLE!!!!! =

A matchstick has a lot of chemical energy stored in it. When the match is struck, it burns and the chemical energy in it produces heat energy and light energy = = Candles also possess a lot of chemical energy. So does petrol.

= WHAT IS CHEMICAL ENERGY??? =
 * Chemical Energy** is energy stored in the bonds of atoms and molecules. Biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Chemical energy is converted to thermal energy when we burn wood in a fireplace or burn gasoline in a car's engine.

Chemical energy is the result of atoms and molecules interacting. This is the most used energy around us. It can be found in batteries, food, and plants

Our food contains the chemical energy we need to live, grow and move.

=HOW IS CHEMICAL ENERGY USED????=

Of all the forms of energy today, chemical energy is by far the most commonly used. It is found in batteries and handheld devices and their chemical reactions, or in the millions of uses developed for fossil fuels.
